At Macrostax, when we create your custom macro plan, we use age, gender, height, weight, activity level, and goal settings. However, we do not take into account any medical conditions that may impact your nutrition requirements. You may still be able to use Macrostax, but we recommend consulting with your doctor or dietitian for individualized advice and macro targets or finding out if a high carb/moderate protein/low-fat diet will work for you.
